My wife, two poodles, and I will be transitioning from town to a 12 acre plot. The land is hilly and slopes in three directions (south, west, and north), from gradual to steep and at the highest point is about 100 ft higher than the road we use to get there. On the north side, there is a creek bed, beautifully layered limestone, which flows when there's a rain, holds water for a few days, and then it's dry. There's an excellent pocket or two where I can imagine slowing the flow and having a dam, but like I said, it's all limestone. While there are lots of old oaks and hardwoods around this creek bed (for leaf litter to fall in) I wonder about the "pond-ability" of limestone. I know it's well known for doing anything but holding water. Will leaf littler eventually help? Or, is some liner necessary for any semblance of water storage? Any help is appreciated.
